Principal, Technical Architect - Application and Integration

This is a strategic, hands-on architecture role where the Principal Technical Architect will lead the design and delivery of complex enterprise solutions, focusing on cloud-native applications, microservices, and integration platforms. The role involves working closely with business and technology teams to create scalable, practical solutions that support the organisation's long-term ambitions.

Responsibilities

• Lead the architecture and delivery of complex enterprise solutions, owning technical design from concept through to production deployment.
• Design and evolve microservices-based architectures, including domain decomposition and service boundary definition.
• Apply Domain Driven Design (DDD) principles to model business domains, define bounded contexts, and create scalable, maintainable service ecosystems.
• Design robust integration solutions using both synchronous and asynchronous communication patterns.
• Shape API-first architectures leveraging REST APIs, GraphQL, API gateways, messaging platforms, and event streaming technologies.
• Define data ownership, persistence, and integration strategies across distributed systems and enterprise platforms.
• Partner closely with Product Owners, Business Analysts, engineering teams, and other stakeholders to translate business requirements into practical architectural solutions.
• Guide development teams through implementation, ensuring solutions remain aligned with architectural principles, quality standards, and business objectives.
• Drive adoption of cloud-native architecture patterns across applications, integrations, and digital platforms.
• Evaluate emerging technologies, tools, and engineering practices, including AI-assisted software development capabilities.

Requirements

• Proven experience as a Technical Architect delivering multiple projects end-to-end, from architecture design through to successful production implementation.
• Extensive experience architecting large-scale microservices-based solutions within complex enterprise environments.
• Strong expertise in Domain Driven Design (DDD), including bounded contexts, aggregates, domain modelling, and service decomposition.
• Expert-level knowledge of enterprise integration architecture, including both synchronous and asynchronous integration patterns.
• Hands-on experience with modern integration technologies such as REST APIs, GraphQL, API gateways, messaging platforms, and event streaming solutions (e.g., Kafka, Azure Event Hubs, or equivalent).
• Strong data modelling skills with experience defining data ownership, persistence strategies, and integration approaches across distributed systems.
• Significant software engineering background, including hands-on development experience in Java, .NET, or a comparable backend technology.
• Experience working across the full software delivery lifecycle, from design through implementation and production support.
• Strong understanding of modern cloud platforms, with experience on Azure preferred, although AWS or GCP experience will also be considered.
• Knowledge of cloud-native architecture patterns including containers, orchestration platforms, managed messaging services, and observability tooling.
• Ability to communicate effectively across audiences, from highly technical engineering teams to business stakeholders and product leaders.
• Strong stakeholder management skills with the ability to explain architectural decisions, trade-offs, and recommendations clearly and appropriately for different audiences.
• Experience working with modern frontend frameworks such as Angular or React, enabling effective collaboration across full-stack engineering teams.
• Exposure to highly distributed, event-driven, and real-time processing architectures.
• Experience with enterprise-scale cloud transformation, modernization, or platform engineering initiatives.
• Practical experience using AI-assisted development tools such as GitHub Copilot, Claude Code, or similar technologies.
• Experience within financial services, banking, or other highly regulated industries.
• Architecture certifications such as TOGAF, Microsoft Certified: Azure Solutions Architect, AWS Solutions Architect, or equivalent.
